Abstract: In order to explore the correlation mechanism between different garlic bolt harvesting methods, leaf damage degree, and average bulb weight, a twoyear garlic field experiment was carried out. Two garlic varieties, “Cangshan white garlic” and “Jinxiang purple garlic”, were used as materials to study the effects of 12 kinds of garlic bolt harvesting methods on average bulb weight, such as no harvesting, manual harvesting, knifecutting harvesting, flower budshearing harvesting, and different plant leaf damage degree. The experimental data showed that each harvesting method had different effects on average bulb weight. The average bulb weight was the highest when using the flower budshearing method and the lowest when using the no harvesting method. The difference between the two methods was significant. There was no significant difference between the manual harvesting method and the knifecutting harvesting method. There was a significant negative linear correlation between leaf damage degree and bulb average weight. The results can provide a basis for optimizing the combined harvesting method of garlic bolt and garlic bulb and provide a data reference for the study of garlic bolt harvesting machinery.

摘要： 为探究蒜薹不同采收方式及植株叶片损伤程度与鳞茎均重之间的关联机制,开展两年的大蒜田间试验研究。试验以"苍山白蒜"和"金乡紫皮蒜"两个大蒜品种为材料,研究不采薹、手工采薹、犁刀法采薹、剪花苞式采薹及不同植株叶片损伤程度等12种蒜薹采收方式对鳞茎均重的影响。试验数据均表明,以鳞茎均重为评价指标,各采收方式对评价指标均有不同程度的影响。剪花苞式处理组指标值最高,不采薹处理组指标值最低,且两组指标值差异显著;手工采薹与犁刀法采薹的指标值差异不显著。植株叶片损伤程度与指标值呈显著负线性相关关系。研究结果为优选蒜薹和鳞茎的组合采收方式提供依据,同时也为蒜薹采收机械的研究提供数据参考。
